swift - Firebase .setvalue 未上传

Question

我有 19 个文本字段想要上传到 Firebase 数据库。起初我写了这个 ref.child("Coupons").child(self.countyyryr.text!).child(self.childx.text!).setValue(["company name": self.companyname.text ，“类别”:self.category.text，“电子邮件”:self.email.text，“电话号码”:self.phonenumber.text，“小时”:self.hours.text，“ Logo ”:self.logo.text ，“yelplink”:self.yelplink.text，“totaloffer”:self.totaloffer.text，“cp0name”:self.cp0name.text，“cp0code”:self.cp0code.text，“cp0amount”:self.cp0amount.text , "cp0picture": self.cp0picture.text, "cp1name": self.cp1name.text, "cp1code": self.cp1code.text, "cp1amount": self.cp1amount.text, "cp1picture": self.cp1picture.text ])

并且 xcode 被卡住了索引。然后我将上传功能分成两个:

ref.child("Coupons").child(self.countyyryr.text!).child(self.childx.text!).setValue(["company name" : self.companyname.text, "category" : self.category.text, "email" : self.email.text, "phonenumber" : self.phonenumber.text, "hours" : self.hours.text, "logo" : self.logo.text, "yelplink" : self.yelplink.text, "totaloffer" : self.totaloffer.text])

ref.child("Coupons").child(self.countyyryr.text!).child(self.childx.text!).setValue([""cp0name" : self.cp0name.text, "cp0code" : self.cp0code.text, "cp0amount" : self.cp0amount.text, cp0picture" : self.cp0picture.text, "cp1name" : self.cp1name.text, "cp1code" : self.cp1code.text, "cp1amount" : self.cp1amount.text, "cp1picture" : self.cp1picture.text])

只有第二个函数正在上传。我尝试添加延迟以查看互联网连接是否有问题，但是第二个功能仍然是唯一的上传功能。然后我尝试制作 3 个不同的函数，但现在它们都没有上传。以下是我当前的代码，感谢任何帮助。

两个函数都在执行，但您通过将值设置为其他值来覆盖路径的值。设置路径值后，可以使用 .updateChildValues 而不是 setValue，或者将更新合并到单个字典中并一次性设置所有值。

func uplo() {
    print("reading one")
   ref.child("Coupons").child(self.countyyryr.text!).child(self.childx.text!).setValue(["company name" : self.companyname.text, "category" : self.category.text, "email" : self.email.text, "phonenumber" : self.phonenumber.text, "hours" : self.hours.text])

}
func sed() {
    print("reading two")
    ref.child("Coupons").child(self.countyyryr.text!).child(self.childx.text!).updateChildValues(["logo" : self.logo.text, "yelplink" : self.yelplink.text, "totaloffer" : self.totaloffer.text, "cp0name" : self.cp0name.text, "cp0code" : self.cp0code.text, "cp0amount" : self.cp0amount.text])

}
func dod() {
    print("reading three")
    ref.child("Coupons").child(self.countyyryr.text!).child(self.childx.text!).updateChildValues(["cp0picture" : self.cp0picture.text, "cp1name" : self.cp1name.text, "cp1code" : self.cp1code.text, "cp1amount" : self.cp1amount.text, "cp1picture" : self.cp1picture.text])

}
